The two grabbed some sushi at SushiSamba in Heron Tower and held hands as they left their one-on-one dinner.
The 20-year-old singer wore an especially adorable ensemble for her night on the town.
She dressed in a houndstooth overcoat, nude-colored frock and a pair of sky-high heels to match.
Grande also appeared to have lightened her hair significantly since the last time she was spotted in public. Maybe blondes do have more fun?!
Meanwhile, her boy-bander beau sported a Superdry sweater and jeans, but brought along a chic leather jacket just in case in got chilly.
Things are certainly heating up in Grande's career lately.
She just announced via Twitter that she was nominated for an American Music Award for New Artist of the Year.
"Thank you so much @theAMAs, so excited and honored," she wrote.
And it's only a short time before we know if she nabbed the big award or not. The 2013 AMAs are set to air on Nov. 24.
These two are quite the hot young couple to watch!
